perf: use deque for FIFO queues in sequence parallel, superoffload, and compile (#7880) ## Problem Three files use `.pop(0)` for FIFO queue processing, which is **O(n)** per removal: 1. `ulysses_sp.py`: Micro-batch queue for sequence parallel data sharding 2. `superoffload_stage3.py`: Parameter buffer for IPG gradient bucketing 3. `compile/backend.py`: Compile pass schedule queue ## Solution Switch to `collections.deque` with `.popleft()` for **O(1)** front removal. ## Changes | File | Pattern | |------|---------| | `deepspeed/runtime/sequence_parallel/ulysses_sp.py` | `micro_batches` FIFO queue | | `deepspeed/runtime/superoffload/superoffload_stage3.py` | `params_in_ipg_bucket_buffer` drain loop | | `deepspeed/compile/backend.py` | `remaining_schedule` step-by-step consumption | Signed-off-by: g97iulio1609 <giulio97.leone@gmail.com>
